Abstract (en)
Disclosed is a polymer electrolyte fuel cell having an improved separator plate. The fuel cell comprises a solid polymer electrolyte membrane; an anode and a cathode sandwiching the solid polymer electrolyte membrane therebetween; an anode-side conductive separator plate having a gas flow path for supplying a fuel gas to the anode; and a cathode-side conductive separator plate having a gas flow path for supplying an oxidant gas to the cathode, wherein each of the anode-side and cathode-side conductive separator plates is composed of a metal and a conductive coat which has resistance to oxidation and covers a surface of the metal. Alternatively, the above-mentioned separator plates are formed of a metal and a coat having resistance to oxidation and have roughened surfaces with recessions and protrusions, and portions of a top surface of the protruding portions, which lack the coat, are electrically connected to an electrode. <IMAGE>
